spherical in outline, would be reached between each two 

 nearest emanatiug centres, where the encountering forces 

 would be equal. At these limits or boundaries both trans- 

 mission and reflection would take place; that is, there 

 would arise inverse action in both directions, resulting in 

 thin waves. After the manner of waves, this would com- 

 mence a condensation, followed by a relaxation ; another 

 condensation, followed by another relaxation ; and so on 

 until the final condensation near the centre. As the dis- 

 tances were unequal, the compression would not be spher- 

 ical; the pressures would be unequal from different sides, 

 and rotation would be the consequence, giving rise to 

 numerous bodies of various sizes, the planets and asteroids 

 of our system. The waves of relaxation and condensation 

 would serve to explain the cold and hot regions of our 

 globe ; for as yet no heat had appeared, but is farther to 

 be explained. 



Let us begin with a solid, and apply heat to it. It takes 

 80° of latent heat to melt ice, represented by gradually 



increasing circles (a), until reaching the liquid state, when 

 the circles will be uniformly equal, the radii and circum- 

 ferences being at identity (b). Continuing the application 

 of heat, the circles enlarge, until the circumferences touch,
